APPARATUS FOR FINISHING CAN-WHEELS AND SIMILAR METAL ARTICLES.

Specification of Letters Patent.

Patented June 18, 1912.

Application filed October 26, 1909. Serial No. 524,724.

To all whom it may concern:

Be it known that I, Enwm E.- SLICK, of Pittsburgh, Allegheny county, Pennsylvania, have invented certain new and useful Improvements in Apparatus for Finishing Car-Vheels and Similar Metal Articles, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

In the drawing a plan View partly in horizontal section is shown of apparatus constructed and arranged in accordance with my invention.

The object of the invention is to provide apparatus for carrying out my improved method having novel means for finishing such metal bodies and. having novel means for centering the supporting the wheels or other metal bodies during thefinishing operation.

In the drawings, 2 represents the base of the apparatus having ways or slides upon which the carriage 3 is mounted, so as to be longitudinally adjustable in a direction parallel to the axis of the Wheel or other article being operatedqfpon, this carriage being adjusted through an adjusting screw and connecting mechanism by the hand wheel 4. Mounted upon the carriage 3 in ways or slides 5 and 6 is a carriage 7, which is arranged to be adjusted transversely .on

its slides in a directlon at right angles to the axis of the wheel or other article'being operated upon. The carriage 7 is connected by an adjusting screw having the'bevel gear 8 on one end, through the gearS' on the shaft 9, and the gears 10, 10, with the hand wheel 11, by which'it is adjusted transversely. Secured in the bearings 12 and 13 on the carriage 7 is a shaft 14 which is connected by the flexible coupling 15 to the armature shaft of the driving motor 16, this motor preferably being mounted as shown on the carriage 7, so as to bemovable longitudinally and transversely with the carriage. On one end of the shaft is a circular metallic disk 17 havin a surface 17*, formed so as to shape the article being operated upon to the desired contour and size.

Mounted in the stationary bearing 18 on the base 2 is a hollow shaft 19, having a worm wheel 20 on one end and meshing with the teeth of the worm wheel 20 is a worm on the shaft 21, which is connected the motor 23. The hollow shaft 19 is provlded with a thrust collar 19, by which end thrust on the'shaft is transmitted through the roller thrust bearing 24 to the bearing 18. Secured in ways or slides 25 on the base 2 of the apparatus so as to be longitudinally adjustable is a bearing 26 having a shaft 27. The shaft 27 is constructed and arranged in the bearing 26 and is provided' with a thrust collar and roller thrust bearmg m a similar manner to the shaft 19 and.

one end of this bearing 26 is connected. to one end of the piston rod 28 havin apiston 29 which is reciprocated in the uid pressure cylinder 30, also secured on the base 2, fora purpose described later. The opposto and rotated by the armature shaft 22'of ing ends of the shafts 19 and 27, which shafts are in alinement, are provided with flanges 19, 27 and inserted in the registering central openings in these shafts are centers 31, 32, having projecting conical ends. The center 31 is detachably' secured in place on the shaft 27, and the center 32 is attached to one end .of the rod or shaft 32, which extends through the opening in the hollow shaft 19, so as to move longitudinally with the rod. A spiral spring 33 in the recessed opening in the shaft 19 is arranged to press the center 32 forwardly when this center is not employed in holding a wheel or other body in position while being finished or machined. Secured in place on the flange 19 of the shaft 19, so as to rotate with this shaft is a disk or ring 34,against which the side of the wheels are held secured during the finishing operation, by means of the center 31 I and shaft in the axially adjust-able bearing 26.

Vater, oil or other cooling medium is supplied through the pipe 37, which is connected to a source of supply, to the omt of application on the article being finished, the supply being regulated by means of the valve 38. I

In the operation of the apparatus, the center 31 is retracted by means of the plston rod 28, and piston.29 in the cylinder 30. The wheel or other article to be finished is then swunginto position,.so that the bore of the wheel surrounds the center 32, thecenter 32 being caused to project forwardly by the action of the spring 33,- when the wheel is being putinto position. Fluid pressure is admitted to the cylinder 30 to advance flanged end of the shaft 19. The fluid presa rate of several miles per "minute.

. Modifications in the construction rangement of the parts'may be made withsure in the cylinder 30 holds the wheel or other article'in this position during the finishing or'machining operation. a The motor 23 is then caused to rotate-and the motor 16 ,is started in operation so as to revo ve the metal disk 17 at a very high rate ofspeed,

preferably such that its peripherymovesfiat 3' means of the hand wheels 4 and 11, the 'pe-' riphery 17 of the metal disk 17 is brought into engagement with the periphery of the article to befinished. As the rapidly revolving peripheral surface of the disk 17 contacts with that of'the wheel or other article, the action of the contacting disk removes Surplus metal from the wheel and finishes itto the desired size, The'periphery 17 of the disk 17 is formed to the desirednontourof the flange and thread of the wheel whensuch. article is being finished. The center 31 is then retracted and the wheel is removed from :the centers 31 and 32, and another wheel or similar article is placed in position, -when the above described operations are again carried out.

and arout departing .frornmy invention. The size and s ape of the metallic finishing disk may be varied and the. means employedin revolving this disk may be changed, and' other changes may be made within the scope Ofxthfi claims.

- 'I claim:-

1. f Apparatus for I finishing cylindrical articles, comprising a rotarysupporthaving' opposingshaft's, centering pins on the ad-. ace'nt-ends f'said shafts, means. for 'pos'i-fz tivelylrotatmg 'at least, one of said shafts,-

and means for'rela-tivel movin said shafts,

:longitudinally into an out o supporting.

7 being arranged to-movelongitudmall and simultaneously i'n' one' and position, said centering, pinst e'same tion,"when cles, a flat disk on said support, and fluid pressure means for moving and holding the articles bein finished in frictional engagement with said disk during the finishing op-' erations, a centering pin mounted insaid disk in axial alinement therewith and longitudinally movable relative thereto, and means yieldingly holding said pin in its extended position.
